Objective: To observe the clinical efficacy of grain-sized moxibustion in treating chemotherapy-induced myelosuppression for non-small cell lung cancer (NSCLC) and its effect on quality of life (QOL). Methods: Eighty NSCLC patients admitted to the Inpatient Department of Zhejiang Cancer Hospital between September 2016 and March 2018 were recruited and divided into an observation group and a control group by random number method, with 40 cases in each group. The two groups both received chemotherapy with paclitaxel plus cisplatin (TP regimen). The control group received oral administration of leucogen tablets starting from the first day of chemotherapy, 20 mg each time, three times a day, for consecutive 14 d; the observation group was additionally given grain-sized moxibustion, once a day, five days per week at a two-day interval, until the fourteenth day. The myelosuppression severity was observed and compared between the two groups prior to chemotherapy, at the 3rd, 7th and 14th days of chemotherapy; the QOL in the two groups was evaluated before chemotherapy, at the 14th and 21st days of chemotherapy. Results: Regarding myelosuppression, the peripheral blood indicators increased significantly at the 3rd day of chemotherapy in both groups (P<0.05 or P<0.01); at the 7th and 14th days of chemotherapy, the peripheral blood indicators presented a decreasing tendency in the two groups, but the level in the observation group was still significantly higher than that before chemotherapy (P<0.01); at the 3rd, 7th and 14th days of chemotherapy, the peripheral blood indicators in the observation group were higher than those in the control group (P<0.05 or P<0.01); the occurrence rate of myelosuppression in the observation group was significantly lower than that in the control group (P<0.01). The QOL score in the observation group was markedly higher than that in the control group at the 14th and 21st days of chemotherapy (both P<0.05). Conclusion: Grain-sized moxibustion can effectively improve myelosuppression after chemotherapy for NSCLC, reducing its occurrence and enhancing the patient's QOL.

Objective To investigate transcriptional expression and promoter CpG methylation status of A-kinase anchoring protein 12 (AKAP12) gene and analyze their correlation with clinical pathological stage in bladder transitional cell carcinoma. Methods AKAP12 mRNA expression level and promoter CpG metbylation status was measured by fluorescent quantitative RT-PCR (FQ-RT-PCR) and methylation specific PCR (MSP) in 30 bladder transitional cell carcinoma and adjacent normal tissues. The products of PCR were cloned and bisulfite sequenced. Results Decreased AKAP12 mRNA expression was demonstrated in 22 carcinomas (73. 3% ) and was significantly associated with turnout grade (P =0. 02).The frequency of promoter methylation of AKAP12 gene was 53. 3 % (16/30) and correlated with the tumor stage(r =0.52,Pn =0.03)and grade(r =0.61,Pn =0.01). Conclusion Aberrant promoter methylation of AKAP12 can result in the loss of gene expression and may association with bladder transitional cell carcinoma.

BACKGROUNDThere are few studies to assess whether the effect-site concentration of propofol can predict anesthetic depth during the target-controlled infusion (TCI) induction in elderly patients. This study aimed to evaluate the relationship between effect-site concentration of propofol and depth of anesthesia during the TCI induction in elderly patients.

METHODSNinety patients (60 - 80 years) with an American Society of Anesthesiologists (ASA) physical status of 1 - 3, undergoing scheduled abdominal and thoracic surgery under general anesthesia were randomly allocated into one of three groups, Group S1, S2 and S3 (30 patients in each group). The patients in Group S1 received propofol with a target plasma concentration of 4.0 microg/ml; patients in Group S2 received propofol with an initial target plasma concentrations of 2.0 microg/ml that was raised to 4.0 microg/ml 3 minutes later; patients in Group S3 received an infused scheme of 3 steps; starting from a target plasma concentration of 2.0 microg/ml that was increased stepwised by 1 microg/ml until a target plasma concentration of 4.0 microg/ml was achieved, the interval between the two steps was 3 minutes. When an Observer's Assessment of Alertness/Sedation (OAA/S) score of 1 was achieved, remifentanil (effect-site concentration (Ce) of 4.0 ng/ml) and rocuronium 0.9 mg/kg were administered. Tracheal intubation was started 2 minutes after rocuronium injection. Changes of propofol Ce, blood pressure (BP), heart rate (HR), and bispectral index (BIS) were recorded.

RESULTSWhen an OAA/S score of 1 was achieved, Ce of propofol were (1.7 +/- 0.4) microg/ml, (1.9 +/- 0.3) microg/ml, (1.9 +/- 0.4) microg/ml and the BIS values were 64 +/- 5, 65 +/- 8, and 62 +/- 8 in Groups S1, S2 and S3. Before intubation, Ce of propofol was (2.8 +/- 0.2) microg/ml, (2.8 +/- 0.3) microg/ml, (2.7 +/- 0.3) microg/ml, and the BIS values were 48 +/- 7, 51 +/- 7, and 47 +/- 5 in Groups S1, S2 and S3. By linear regression analysis, a significant correlation between Ce of propofol and BIS values was found (r = -0.580, P < 0.01). Systolic blood pressure (SBP) before intubation was significantly lower in Group S1 than in Groups S2 and S3. SBP and HR after intubation in the three groups were significantly increased when compared with pre-intubation values, but they did not exceed baseline values.

CONCLUSIONSDuring the TCI induction, Ce of propofol with (1.9 +/- 0.3) microg/ml may make the elderly patients unconscious. When remifentanil with a Ce of 4.0 ng/ml is added a Ce of propofol with (2.8 +/- 0.3) microg/ml is suitable for intubation. The Ce of propofol has a close correlation with the BIS values. Also, a two-step TCI technique seems to be a more suitable method of anesthesia induction in elderly patients compared with the no-stepwise TCI technique and three-step TCI technique.

This study was aimed to construct the shRNA eukaryotic expression vectors of M2-pyruvate kinase gene (pkm2) and to investigate the effects of pkm2 gene interference on the drug resistance of acute promyelocytic leukemia (APL) cells in vitro. Three specific shRNAs of pkm2 gene were designed and cloned into PBSU6 vector containing a U6 promotor. The constructed plasmids were identified and proved by the restriction sequence analysis. Then the effect of pkm2-shRNA on the protein expression of endogenous PKM2 was detected in NB4R2 cells, a drug resistant cell line of APL by Western blot. The alteration of NB4R2 cell differentiation with the interference of pkm2 gene was also validated by nitroblue tetrazolium (NBT) reduction test. The results showed that three specific shRNA eukaryotic expression vectors targeting pkm2 were successfully constructed. The efficiency of pkm2 gene silence was proved at protein level. The interference of pkm2 gene could significantly enhance the cell differentiation in the drug resistant NB4R2 cell line. It is concluded that the DNA vector containing pkm2 targeting shRNA remarkably promotes the differentiation of NB4R2 cells, showing the prospects of developing the gene target drug.

OBJECTIVETo verify Working Group for Obesity in China (WGOC) recommended body mass index (BMI) classification reference for overweight and obesity in Chinese children and adolescents using the data of 2002 China Nationwide Nutrition and Health Survey.

METHODSPediatric metabolic syndrome (MetS) and abnormality of each risk factor for MetS were defined using the criteria for US adolescents. Definition of hyper-TC, LDL, and dyslipidemia in adults was applied as well. The average level and abnormality rate of the metabolic indicators were described by BMI percentiles and compared with general linear model analysis. Receiver operating characteristic analysis was used to summarize the potential of BMI to discriminate between the presence and absence of the abnormality of these indicators.

RESULTSThere was neither significantly increasing nor significantly decreasing trend of biochemical parameter levels in low BMI percentile range (<65th). Slight increasing trend from the 75th and a significant increase were found when BMI > or =85th percentile. In general, the prevalence of the examined risk factors varied slightly when BMI percentile<75th, and substantial increases were consistently seen when BMI percentile > or =75th. As an indicator of hyper-TG, hypertension and MetS, the sensitivity and specificity were equal at the point of BMI<75th percentile, and the Youden's index of risk factors also reached peak point before 75th percentile except for MetS. When the BMI percentile was used as the screening indicator of MetS, Youden's index reached peak point at 85th percentile, just the point in the ROC graph that was nearest to the upper left corner.

CONCLUSIONThe BMI classification reference for overweight and obesity recommended by WGOC is rational to predict and prevent health risks in Chinese children and adolescents. Lower screening cut-off points, such as 83th percentile or 80th percentile, should not be excluded when they are considered as overweight criteria in future intervention or prevention studies.

In order to investigate the expression and the relationship of ubiquitin associated protein 1 (ubap1) gene and tumor-suppressor gene p16 in acute leukemia, 68 cases of acute leukemia and 22 control cases were selected in this experiment, FQ-PCR technique was used to detect the mRNA expression level of ubap1 gene and p16 gene in their bone marrow cells. The results showed that as compared with the control group, the ubap1 gene in acute leukemia group highly expressed (p<0.01), while the p16 gene lowly expressed (p<0.01). But grouping of patients according to FAB revealed that as compared with the control group, the ubap1 gene expression displayed statistical difference only in M4 and M5 of adult AML (p<0.05), while the p16 gene expression in all groups of adult AML showed significant difference (p<0.05) except M1 and M2. In addition to this, the ubap1 gene and p16 gene mRNA expression in AL was not relate with chromosome abnormality (p>0.05). A negative correlation (r=-0.827, p<0.01) was found between the ubap1 gene and p16 gene mRNA expressions in the control group. It is concluded that the upregulation of ubap1 gene expression mainly and the downregulation of p16 gene expression mainly may simultaneously participate in the pathogenesis of acute leukemia. High expression of ubap1 gene influences the M4 and M5 subtypes in AML. This discovery provides important theoretical basis for the further investigation of pathogenesis and targeting therapy of AL.
